-TUBULAR WOVEN FABRIC.

SPECIFICATION forming @met Letter; Patent Naciones, date september e,189s. Application .filed J'uly25,1898. Serial No. 686,815. (No model.)

T0 a/ZZ whom it may concern:

Beit known that I, BENJAMIN `L. STOWE'," of Jersey City, in the State ofNew Jersey, have invented a new and useful Improvement in Tubular WovenFabrics, of which the following is a speciication.

My present invention relates to woven fabric for hydraulic or fire hoseprovided with an interior surface free from the furrows or corrugationswhich appear on the interior surface of ordinary tubular woven fabric,thus furnishing a smooth surface upon which theV rubber lining can belaid. Y

In another application for Letters Patent, filed March 3l,`1898,"Serial=No. 675,885, on which Letters Patent will issue of even date herewith, Ihave Ydescribed and claimed a tubular woven hose fabricv in which thewaterway is rendered smooth and free from corrugations by incorporatinginto the fabric leveling weft-strands, laid on the interior surface ofthe tubular fabric in the furrows or corrugations between the severalfilling-strands of are held in place in the fabric extend through to theexterior of the fabric. In my present improvement the warps which holdin place the said leveling strands do not extend through to the exteriorof the fabric, but stop short of the outer ply thereof, the advantage ofthis improved arrangement being that the wearing away of the outer plyor plies will not destroy or impair the warps which hold the levelingfilling or weft strands.

In the accompanying drawings, to which I shall now refer for a betterunderstanding of my said improvement, Figure l represents inlongitudinal section a piece of tubular-woven fabric rubber-linedhydraulic hose embodying my improvement. Fig. 2 is a longitudinalsection of the fabric on a scale more en- Alargedthan inFig. 1.

In the drawings, and particularly in Fig. 2, the strands are representedon an enlarged scale and widely separated from one another inorderthatthe structure of the fabric may bemore. readilyunderstood. In theactual fabric the strands are of course packed closely together.

In Fig. 1 R is the rubber lining.

The fabric shown in the drawings is one which without the addition ofthe strands requisite to effectuate myimprovement would would be anordinary multiply (in this instance three-ply) seamless hose, the threeplies of which are lettered A, B, and C. The regular warp and weft ofthe inner ply are lettered a and b, respectively. The regular warp andweft of the intermediate ply are let tered d' and b', respectively. Theregular warp and weft of the outer ply are lettered c2 and b2,respectively, and the bindingstrands which bind the plies together arelettered e.

In the fui-rows or corrugations between the filling-strands b of theinner ply and upon the interior surface of said ply I lay, during theprocess of weaving the fabric, an additional filling c, whichis held andincorporated into the fabric by warp d. The warp d and the filling cthus added to the fabric will 'preferably be of fine'yarn, justsufficient in size, when incorporated into the fabric, to fill thefurrows between the ordinary lling yarn or yarns b on the interior`surface of the hose fabric, thus ,making this surface practically smoothand without corrngation. The strands CZ stop short of the exterior ofthe fabric and do not appear in the outer ply. Indeed they are in theillustration of my invention given in the drawings confined to theinnermost ply A exclusively and do not appear in either the intermediateply B or the outer ply C. The result of this improved arrangement of thewarp-strands d is that they will not be destroyed or impaired by thewearing away of the outer ply or plies of the fabric.

I-Iaving described my improvement, I desire to state that I do notconfine myself to the exact structural details shown in the accompanyingdrawings in illustration hereof; but i What I here claim, and desire tosecure by Letters Patent, is

1. Tubular Woven fabric for fire `or hydrau lic hose having incorporatedin its structure IOC) leveling weft-strands laid on the interior surfaceof the tubular fabric in the furrows between the usual filling-strandsof said fabric, and Warp-strands for holding said levelingstrands whichstop short of, and do not extend through to, the exterior of saidfabric,

substantially as and for the purposes herein before set forth.

2. Tubular multiply Woven fabric for hydraulic or lire hose havingincorporated in its structure leveling weft-strands laid on the interiorsurface of the inner ply in the furmy hand this 21st day of July, 1898.
